As part of the ongoing mitigation of the Spectre and Meltdown attacks (https://meltdownattack.com), our hosting provider has scheduled a reboot of one of our database servers. During that time new feeds won't be crawled and posts won't load properly. The reboot has been scheduled for 2018-01-18 05:00 AM UTC and we estimate it will take around 30 minutes.

Again, we're really sorry for the short notice. We're notifying you as fast as our hosting provider schedules these windows.
